and a clamping nut 19 on the inner or under side of the felly. Preferably the shank of the spreader is made integral with and constitutes the stem of the usual inflat-ing valve, the same being herein shown as covered and protected by the usual tubular dust-cap 20. The spreader 16 has the function not only oi spreading the side Walls of the tire and clamping them hard against the side-rings 9 but it= also gr'ps the tire seeurely to the rim and preventseree' ing.

In Fig. 2 I have sown, in lieu of the latsurfaced side-rings 9 of Fig. 1, interchangeable side-rings of clenclier form, designated by 21; this latter type of sidelring being equally applicable for use in connection Wit-h the loclring-ring l1, as plainly shown; the entire construction producing a rim of the clencher type with the described advanta es of easy and quick detachability and app ication of the tire when desired.

From the foregoing it Will be seen that my invention provides a simple and easily manipulated fastening means for tires, which renders the latter easily and readily detachable, and which is quickly interchangeable to accommodate either the groved or plain-surfaced form of 'res by simply interchanging the side or fill r-rings emesse 9 and 2l. It Will be evident that the principle of the invention can readily be eX- tended to still other forms of filler-rings than those herein shown adapted for engagement and cooperation with still other lforms or types of tires; it being understood 'ble locking-,ring engaging the outer side of said filler-rin throughout substantially the full Width o the latter, said locking-ring having a bead seated in said groove and a square annular shoulder resting against the portion of said rim outside of said groove, and pins connecting said locking-ring and filler-ring, substantially as described.
